  摘要：

  本研究通过自由基聚合法制备了一种新型接枝共聚物固体电解质，它具有相对较高的离子电导率，在 30 °C 时为 10-3.9 S cm-1，在 80 °C 时为 10-3.1 S cm-1。该聚合物以甲基丙烯酸酯为骨架，以一定比例的十六烷基（C16）-甲氧基端寡聚（环氧乙烷）混合物为侧链。傅立叶变换红外光谱（FTIR）和差示扫描量热法（DSC）分析表明，非极性单元（C16）端改性不仅大大提高了环氧乙烷（EO）链的流动性，而且通过打断其规则排列抑制了其局部结晶行为，从而提高了所获电解质的导电性。

  A metal fine particle dispersant is obtained by reaction of a polymer (a) containing a first reactive functional group, an ionic group to be absorbed to metal fine particles, and a polyoxyalkylene side chain with a compound (b) containing a second reactive functional group to be bonded to the first reactive functional group and an active energy ray curable group to be cured by an active energy ray. A metal fine particle dispersion liquid containing the metal fine particle dispersant, metal fine particles, and a dispersion medium is prepared. The metal fine particle dispersion liquid is cured, thereby obtaining a cured film.
